Title: Hiroshi Adachi: Patents in Music Information and Magnetic Sensing

Introduction

Hiroshi Adachi is an inventor associated with Hamamatsu, Japan, and Yamaha Corporation. His patent work includes technologies for organizing music information and manufacturing compact magnetic sensors. The provided data lists 5 patents for Adachi.

Latest Patents

“Database Constructing Apparatus and Method” describes a way to build a music information database using search words gathered from information source sites. The system associates those words with particular music pieces, enabling searches based on impression words that describe how the music sounds. The approach is intended to make such a database easier and less costly to construct.

“Manufacturing Method for Magnetic Sensor and Lead Frame Therefor” concerns assembling magnetic sensor chips on stages supported by interconnecting members. During manufacturing, the stages are pressed into a common plane so the chips can be bonded and wired; after pressure is released, the members return toward their original positions. The resulting sensor combines chips to detect magnetism in three directions, supporting three-dimensional measurements while aiming to reduce size and manufacturing cost.

Career Highlights

Adachi’s listed inventions span two distinct areas: music-information retrieval and magnetic-sensor manufacturing. Both patents describe practical methods for improving how a system is built or used, from searching music by impressions to producing sensors capable of measuring magnetic direction in three dimensions.

Collaborations

The provided information identifies Kenichi Shirasaka and Hiroshi Saitoh as Adachi’s coworkers. It does not specify their roles in the listed patents.

Conclusion

Hiroshi Adachi’s patent record reflects work on both music database construction and magnetic sensing, with inventions focused on making information retrieval and sensor manufacturing more practical.
